If you can make the set act up by flexing the board, it certainly sounds like a bad connection. I worked on this specific set before and am well aware of some problems with it. You say you could not find any bad connections.... but do you know HOW to locate them ? Some joints can look perfectly normal to someone who is not experienced but be in fact a bad joint. I don't know how this works...but for a small cash fee arranged through this site, I can give you more specific information on what to look for.

How do I replace a broken circuit board on a Sharp LC-60E78UN TV?


You can either remove the power supply and check and replace caps and most likely the transformer (pop sound). Or a replacement can be found on eBay, amazon, etc... One model TV can have numerous diff power supply models from revisions and improvements. If you replace the board make sure you look match serial numbers on board to the new board. The back of the TV will come off very easy. Lay TV face down on a flat surface(making sure nothing is touching the LCD) remove screws. (Make sure cable coax slides free, some have a retainer but to remove) once the back is off the layout should be so simple, you should have no problem identifying parts.

Sharp Aquos television model number LC-37D65E, keeps switching itself off. Can you help?


Hi,

This issue is related to a power problem in as much as the TV turns off on it's own.

The problem is consistent with overheating on the power supply board of the TV.

The power supply board of the TV has few capacitors and IC. If any of these IC's gets short or become weak, it can cause the TV to turn off on it's own.

When current passes from electric outlet to the power supply board of TV. The current also goes to the weak/faulty part, then the current stops or slow and the board overheats and TV shuts off on it's own.

This is a common problem faced by many other users too. To solve this issue, check the power supply board and read it with a meter and continuity tester, in order to detect the faulty part and replace the faulty part on the board which is short due to which power supply board

It's a bit technical job but yes its not at all a costly repair to do or get it done by the technician.

You can buy these part at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress.

Regards.

I have a sharp aquos 37 lcd and one day I turn it on and hear a pop sound and it went dead no power


Normally this is indicative of a faulty power supply circuit inside your TV.

The easiest way to test this is to remove the rear access panel on the TV and replace the power supply circuit board with a new one.

You can find a replacement circuit board on Ebay by searching for your TV's model number.

Here is a link to one currently available for about $100 plus shipping:


http://cgi.ebay.com/DPS-178APA-Power-Board-Power-Supply-Sharp-LC-37D43U-/260814504762?pt=LH_DefaultDomain_2&hash=item3cb9c1833a

Just use your mouse to click on the link, which is the underlined and highlighted text just above. This will open a new web browser page automatically for you and allow you to view the information and items at the website indicated.

The repair / replacement procedure is not extremely difficult if you have some basic electrical safety knowledge and some basic electronics / mechanical repair skills.

You will need to unplug the power cord from the unit, lay the TV screen side down on something soft and flat like a bed, and then remove the rear access panel or the entire rear cover as required in order to access the circuit boards inside.

When you remove the rear cover and access the circuit boards inside, just check the part number that is printed right on your power supply circuit board itself and confirm that it exactly matches the one provided in the Ebay listing.

Then unclip and remove the various electrical wire connectors leading to the power supply circuit board. Then remove the screws securing the circuit board to the TV frame and then remove the power supply circuit board. Be sure to avoid touching any large capacitors on the circuit board which can retain a nasty charge even after the unit is unplugged.

Then just screw in the new circuit board and connect all the wire bundles to their appropriate connectors on the new circuit board and then replace the rear cover. Then plug in the power cord and test.

One other thing you can check is to see if there is a fuse fitted on your set.

Some models will have a fuse holder compartment accessible from the rear of the set right where the power cord enters the enclosure. If your set does not have one of these, then the fuse may be located directly on the power supply circuit board itself.

Try testing that fuse for continuity with a voltmeter (with the set unplugged of course). If that fuse has failed, then it will test OPEN. If you are lucky, you may then just need to buy an exact replacement fuse and then install / solder that into place to correct the problem

I hope that was helpful to you, good luck.

Joe.
